Requirements
CD changer and factory phone plug
Introduction
Safety comes first when you’re on the road, so having an intuitive and easy to
use Bluetooth kit is essential to reducing driver distraction. The BT45-JAG kit is
compatible with virtually all Bluetooth phones, and sounds great whether you are
using it for mobile conversations or music streaming. The system will mute
upon initiating or receiving a call and announces callers phone number on car
speaker. The wireless remote control conveniently installed on dashboard is
used to launch Voice Recognition application (Siri, Google Now, Assistant etc.),
initiate phone calls launch applications, track selection and more. Thanks to the
BT45-JAG Kit users keep the radio and car they love while enjoying Bluetooth
features only available on newer cars.
The BT45-JAG requires a working CD changer (which remains connected
but will no longer play) and factory phone plug (under center armrest)
See Frequently Asked questions at the end of this guide
Notes:
- Vehicle must have a phone plug beneath armrest
- Required CD changer remains connected but will no longer play.
Audio module installation
1. Remove carpet trim piece around audio rack (See Fig. 1). If vehicle does not
have GPS, use empty slot to access changer plug, however vehicles with
Navigation or convertibles, may require lowering audio rack by removing (4)
8mm and leaning rack forward to reveal wiring.
Fig. 1
2. Locate short CD pigtail. Connects CD changer to radio (Standard systems)
or to amplifier (Premium system).
This is the cable required to complete install (See Fig. 1A)

plug/connector location

3. Remove cable from holding tab
4. Disconnect CD changer by gently pulling apart (Don’t wiggle or twist)
5. You should not have cable as seen in Fig. 2. Female connector (right) –
from CD changer, male plug (left) –to amplifier or radio
Fig. 2
6. Connect factory Male plug (See Fig. 2) to audio module female connector.
To connect, simply align markers and push in (avoid twisting)
7. Connect audio module right-angle plug (See Fig. 3b) to CD changer female
connector in Fig. 2
Warning: Our right-angle male plug (See Fig. 3b) does not have an
alignment arrow indicator; however, imaginary arrow seen in Fig. 3b
must align opposite arrow indicator on factory CD changer connector
in Fig. 2 Once aligned mate both (do not twist).
Fig. 3b
8. Return cable to holding tab
9. Connect supplied 3.5mm audio cable (See Fig. 4) to audio module 3.5mm
jack (See image below)
10. Proceed to next step (routing audio cable).
Noteworthy:
They are multiple Ai-Net type plugs/connectors at audio rack and more so
in vehicles with premium systems (e.g., Amplifier, Navigation etc.). In
premium audio systems, audio module (See Fig. 3) connects between CD
changer and amplifier and in standard systems; between CD changer and
radio.
To minimize connecting errors, locate single black cable emerging
from CD auto changer --- seen in Fig. 2 (right). This is the cable with
which you will be working. Connecting audio adapter to something other
than CD auto changer plug will result in volume issues, loss of power (radio)
etc.

Routing audio cable (X308)
1. Use pry tool or similar to open gap between window pillar and rear deck as
seen in Fig. 5. From trunk, fish audio cable (See Fig. 4) through and into
vehicle cabin. (See Fig. 6)
20 ft. audio cable

2. Pull excess and tuck under seat backrest and cushion and work towards
center glove box (armrest) as seen in Fig. 7, Fig. 8 and Fig. 9

3. Continue to use pry tool or fingers to fish wire under center glove box and
into storage bin.
4. To remove storage bin: Open center glove box and remove 2 Philips head
screws from latch cover and two more from hinge then remove single
screw on retainer bracket.
5. Lift to remove storage bin and set aside.
6. Locate audio plug fed through in step 3 and gently pull excess cable.
Note: The aforementioned steps apply to Jaguar XJ (X308). Jaguar XK (X100) –
Convertibles require additional steps not part of this guide.

Frequent asked questions & troubleshooting
1. Why is it important to check factory phone plug? Can this be installed
without one?
Jaguar vehicles are equipped with 4 different phone plugs or connectors
under storage bin (center glove box) and must be verified prior to ordering.
(don’t rely on others with same vehicle). Armed with this information we
are able to include matching plug or connector. If phone plug has been cut,
you may still install this kit, but required to make additional wiring not part
of this guide.
2. Can this be installed without removing radio?
BT45-JAG does not require radio removal. Module installs in storage bin.
3. Which model/year Jaguars will the BT45-JAG work and where do I
connect AUX adapter?
1998-03 XJ (X308) (To CD changer plug in trunk/hatch)
1997*-06 XK (X100) (To CD changer plug in trunk/hatch)
4. Will radio mute when I receive/initiate calls?
YES.When call is initiated or received, radio will mute and “PHONE” is
displayed on radio screen.
5. Will callers name/number display on radio screen?
NO. Phonebook numbers are announced on car speakers.
6. Will I be able to stream music and use GPS apps at the same time?
YES.When streaming and navigating; music will mute during guidance and
return to previous state when guidance ends. If a call is made or received,
both navigation guidance and streaming are muted until call has ended.
7. This kit includes a mini-USB port; can it be used for charging?
NO. Unfortunately, the mini-USB port is for software upgrades.
8. After installing and testing the system everything works, but there is
engine “whine”. What can I do to fix this?
-Ensure volume on audio device is between 90-100% and increase
volume on module using the VOL + on remote control
-Check grounds
-make sure all connections are snug
-switch audio jack to “AUX2” on Bluetooth module
-Install noise filter

9. Will I be able to use overhead microphone in my vehicle instead of
microphone included in this kit?
YES.If kit include option for factory mic, simply connect 3.5mm plug from
installation harness (See Fig. 15) to module “MIC” input.
10. Where is the factory phone plug/connector?
Factory phone plug/connectors are bellow center armrest. ROW and NAS
vehicles may have different plugs; so, we can’t be certain which plug size
or gender applies to your vehicle. Please verify plug/connector size and
gender prior to ordering so that it can be added to your kit. Don’t rely on
others with same vehicle.
In addition, 2000 XK without factory phone will require additional wiring in
trunk so to activate phone plug under storage bin.
11. I realize the CD changer is required for this kit to work, but will I be
able to play CD’s?
NO. This kit does not have option to retain CD playback. Purchase our
A2DIY-JAG98 , JAGCD-HF etc. to retain use of the changer.
*Late 1997 XK (X100) with Ai-NET CD plug only. Early 1997 with 8-pin DIN CD plug do not apply.
